boxx 0.3.0

Versioned Flutter key-value storage with authenticated encryption and change streams.

0.3.0

• SECURITY: Encryption now fails closed and requires at least 32 UTF-8 bytes of key material.
• SECURITY: New AES records use authenticated AES-256-GCM with per-record PBKDF2 salts; Fernet keys are also derived per record.
• FIX: Corrected the IndexedDB schema so web writes use out-of-line keys.
• FIX: Added versioned JSON envelopes that preserve exact value types.
• FIX: Replaced sanitized filenames with fixed-length hashed identifiers.
• FIX: Removed the stale in-memory cache and coordinated change streams across instances and browser tabs.
• FIX: Native writes now use flushed temporary files and atomic replacement.
• NEW: Added named namespaces, structured diagnostics, stable exception categories, and automatic legacy-record migration on read.
• BREAKING: Flutter 3.32 or later is required. Encrypted instances require a 32-byte key. See README migration guidance.

0.2.0

• NEW: Added type-safe generics to get<T>() and put<T>().
• NEW: Added reactivity with watch(key) returning a Stream.
• NEW: Added support for JSON serialization of Maps and Lists automatically.
• NEW: Added keys, values, and all() methods to explore storage.
• IMPROVEMENT: Enhanced memory caching for faster read operations.
• API: Cleaned up internal architecture for better maintainability.

0.1.8

• SECURITY: Fixed critical Fernet decryption vulnerability.
• SECURITY: Implemented random IV for AES encryption (breaking change for previously encrypted data).
• API: Added initialize() method. Initialization is now explicit and async.
• Code: Fixed static state issues for thread safety.
• Docs: Updated documentation and examples.
